Abstract
A control unit for an air conditioning system for a motor vehicle calculates a target blowing air temperature based on a temperature of a passenger's clothing detected by a no contact temperature sensor. An air conditioning operation is performed based on the calculated target blowing air temperature. In particular, when calculating the target temperature in the summer or in the winter season, a change of the detected temperature of the passenger's clothing is used, so that the change of detected temperature is reflected in the target temperature with a time delay.
Claims24
An air conditioning system for a vehicle comprising:
- a temperature switch for setting a desired temperature;
- an air-conditioning unit having a blower device for blowing air into a passenger compartment of the vehicle, the air-conditioning unit further having an evaporator and a heater core for carrying out an air-conditioning operation so as to control temperature of the air blown into the passenger compartment;
- a no-contact temperature sensor for detecting surface temperature of the passenger's clothing;
- and
- a control unit for calculating a target value for temperature of the air blown into the passenger compartment from the air-conditioning unit, the target value being calculated based on the desired temperature and the surface temperature detected by the no-contact temperature sensor so that the air-conditioning operation is carried out by the air-conditioning unit in accordance with the target value,
- wherein the air-conditioning unit continues operation using a time delay before returning to normal operation in such a manner that the time delay in a case of a passenger getting into the vehicle is made larger than the time delay before the passenger gets into the vehicle.
